Comprehensive and multidimensional assessment and measurement of pain.

Current theories of pain and clinical experience support a multidimensional framework for the experience of pain that has implications for assessment and management in any setting. Six major dimensions have been identified: physiologic, sensory, affective, cognitive, behavioral, and sociocultural. Any clinical assessment process must address relevant dimensions of pain in the given setting. In acute care settings, for example, clinicians may focus on physiologic and sensory dimensions, whereas in chronic care settings, the affective, cognitive, and behavioral dimensions might assume priority. Various tools are available for multidimensional assessment of pain, spanning the dimensions of the experience from physiologic to sociocultural. The clinician in any setting must use appropriate tools that provide useful information. Guidelines helpful in a selection process include identification of relevant dimensions of pain, type of pain, patient population and setting, psychometric properties of the tool, and issues of time, clinical relevance, and feasibility. When a careful selection process occurs, the resulting data should simultaneously meet clinicians' needs for information as well as provide the foundation for initiation of multidisciplinary interventions.
